초록
Disclosed is an apparatus for driving a BLDC motor, the apparatus including: a BLDC motor having a single sensing coil therein; a position/speed calculation unit for calculating a current position and a current speed of a rotor by using voltages at both ends of the sensing coil; a control unit for comparing the current speed of the rotor calculated by the position/speed calculation unit with a command speed and then outputting a control signal through a Proportional Integral (PI) control; a motor driving unit for generating a PWM signal based on the current position of the rotor calculated by the position/speed calculation unit and the control signal output by the control unit; and a power device unit for controlling the BLDC motor according to the PWM signal generated by the motor driving unit.
